Работает устройство следующим об- _ разом. 5The device works as follows. 5

Стрелой 1 крана или манипулятора оператор устанавливает устройство над пнем так, чтобы упор 7 располагался приблизительно над его центром. Затем включаются приводы 9, и начинают вращаться шнековые режущие органы 10. В зависимости.от диаметра пня оператор выбирает глубину внедрения шнековых режущих органов 10. Одновременно 1? с включением приводов 9 включается опорный 'гидроцилиндр 5 , -и его шток выдвигается на величину, соответствующую выбранной глубине внедрения, а, следовательно и диаметру пней. K₽o-jQ ме того, в это же время гидроцилйндрами 12 оператор устанавливает соответствующий, диаметру пня раствор шнековых режущих органов 10.Далее оператор врезает шнековые режущие органы 10 в грунт, до того момента, пока упор 7 не упрется в головку пня. Далее гидроцилиядрами 11 шнековые органы, продолжая вращение и резанье, поворачиваются до встречи их нижних концов. После этого включается при- 30 вод б, и вся система начинает поворачиваться вокруг оси вращения вала 3. При этом шнековые органы 10 перерезают корни пня и вырезают конусообраэный ком, соответствующий диаметру пня.35 После этого оператор выключает приводы б и 9 и стрелой 1 извлекает устройство с пнем из земли и направляется его вкучу или после предварительной очистки (например, посредством установ ленного на устройстве вибратора) в кузов транспортного средства. Над этим средством оператор посредством гидроцилиндра 5, 11 и 12 (которые устанавливаются в исходное положение) освобождает выкорчеванный пень.By arrow 1 of the crane or manipulator, the operator sets the device over the stump so that the emphasis 7 is located approximately above its center. Then the actuators 9 are turned on and the screw cutting organs 10 start to rotate. Depending on the diameter of the stump, the operator selects the penetration depth of the screw cutting organs 10. At the same time, 1? with the inclusion of the actuators 9, the supporting hydraulic cylinder 5 is turned on, and its rod extends by an amount corresponding to the selected penetration depth, and, consequently, to the diameter of the stumps. In addition, with the hydraulic cylinders 12, the operator sets the appropriate screw diameter of the screw cutting organs 10 for the stump diameter. Next, the operator inserts the screw cutting bodies 10 into the ground until the stop 7 rests against the head of the stump. Then, with hydraulic cylinders 11, the screw organs, while continuing to rotate and cut, turn until their lower ends meet. After this, the drive 30 is turned on, and the whole system begins to rotate around the axis of rotation of the shaft 3. At the same time, the screw organs 10 cut the roots of the stump and cut out a cone-shaped lump corresponding to the diameter of the stump. 35 After that, the operator turns off the drives b and 9 and removes it with an arrow 1 a device with a stump from the ground and is directed to it vkuh or after preliminary cleaning (for example, by means of a vibrator installed on the device) into the vehicle body. Above this tool, the operator through the hydraulic cylinder 5, 11 and 12 (which are installed in the initial position) releases the uprooted stump.

Предлагаемое устройство имеет сравнительно небольшую Массу и прикладываемые к ее режущим органам усилия резанья, а следовательно является более эффективным по сравнению с известными.The proposed device has a relatively small mass and applied to its cutting organs cutting forces, and therefore is more effective than known.

Claims

The invention relates to a device for harvesting wood and can be used in the forest industry; Known devices for rooting stumps mounted on the boom of a crane or manipulator and including a rigid frame or traverse on which the rotary cutting bodies 1 are symmetrically fixed. The disadvantage of such devices is the low efficiency of work when cutting the roots, mon intended for uprooting. Known devices for trimming, including a rotary shaft with an emphasis, pivotally attached to the shaft levers with cutting bodies and drives of rotation of the shaft and levers 2. The disadvantage of such devices is that when cutting the roots, force-cutting organs require great effort and at the same time the greater mass of the frame hinged on the aim of the invention is an increase in productivity. The goal is achieved by the fact that on each lever there is a hinge mounted holder in which a cutting member is mounted, each holder hingedly connected to the shaft by means of a hydraulic cylinder, which is parallel to the lever, and the cutting bodies are screwed and screwed. The goal is also achieved by the fact that the drive of the levers is made in the form of hydraulic cylinders, which are mounted on the shaft. FIG. 1 shows a general view of the device before introduction into the ground; in fig. 2 - device before removing mon. The proposed device is hinged on the boom 1 through the traverse. 2, in which hall W is installed. Levers 4 are hinged on the shaft 3, as well as onopritdi hydraulic cylinder 5. Vgil 3 can be rotated around the axis of rotation by means of a drive 6 mounted on the yoke 2. The hydraulic cylinder 5 is turned down stem-at its end rigidly an anvil 7 is seated. At the free ends of the levers 4, holders B are pivotally mounted, in which, with the possibility of turning around the axis of rotation, screw-cutting elements 10 are mounted by means of their actuators 9 10. In addition, each holder 8 is pivotally connected to its own hydraulic cylinder of rotation 11. Levers 4 can be rotated by means of a hydraulic cylinder 12. The device works as follows. With the arrow 1 of the crane or manipulator, the operator places the device above the stump so that the stop 7 is located approximately above its center. Then the actuators 9 are turned on, and the screw cutting bodies 10 begin to rotate. Depending on the diameter of the mon, the operator selects the insertion depth of the screw cutting organs 10. At the same time as the actuators 9 are turned on, the reference hydraulic cylinder 5 is turned on, and its uitOK is extended by an amount corresponding to the selected insertion depth , and therefore the diameter of the stumps. Kp, at the same time, the cylinders 12, the operator sets the appropriate, diameter mon solution of the screw cutting bodies 10. Next, the operator smashes the screw cutting bodies 10 into the ground, until the stop 7 stops the head mon. Further, by hydraulic cylinders 11, the screw bodies, continuing rotation and cutting, turn to meet their lower ends. After this, the drive b is turned on, and the entire system begins to rotate around the axis of rotation of the shaft 3. At the same time, the screw bodies 10 cut the roots of the mon and cut the cone-shaped lump that corresponds to the diameter of the mon. After that, the operator turns off the drives b and 9 and removes the device with the boom 1 It is sent from the ground and sent to the vkuchu OR after pre-cleaning (for example, by means of mounting the vibrator on the device) to the vehicle body. Over this tool, the operator through the hydraulic cylinders 5, 11 and 12 (which are set in the initial position) free) rides uprooted stump. The proposed device has a relatively small mass and cutting forces applied to its cutting organs, and therefore is more effective than the known ones. Claim 1.
